I just have a small usuability suggestion for a future release In the "Date Range" implementation, make it so you could pick the either start or end date at any time...
so just say a user choses "Nov 20th" first, then selects "Nov 5th" (whcih currently isn't possible as it "locks out" previous dates), it should be an easy check to flip-flop the dates so the first selection is the end date and the second selection is the begin Just a suggestion to a top notch date picker
